If h=4, then 5(4)+7= 27. Using PEMDAS, do multiplication first, so 20, then add the 7.
7500
the way is multiply the length value by 1000
<span>(3x + 5)(x - 3) = 3x</span>² - 9x + 5x - 15 = 3x² - 4x - 15
Answer: 3x² - 4x - 15
34 x 17 = 578
they would eat 578 kgs a day
X = adult tickets
y= child tickets
x + y = 11
44.95x + 34.95y = 434.45
-44.95x - 44.95y = -494.45
-10y = -60
y = 6 child tickets
x + 6 = 11
x = 5 adult tickets
